Answer:

y = \frac{4}{3}x -7

Step-by-step explanation:

Use the points (9, 5) and (6, 1) to identify the slope of the graph

m = \frac{y^2-y^1}{x^2-x^1}

m = \frac{1-5}{6-9}

m = \frac{-4}{-3}

m = \frac{4}{3}

The y-intercept is -7 because -7 touches y axis causing it to be the y-intercept

cluponka [151]
